MIXING AND CONTROLLING; DEVICE FOR GAS ENGlNES.

SPECIFICATION forming part of Letters Patent No. 679,263, dated July 23, 1901.

Application filed April 21 1899- Serial No. 713,948. (No model.)

To all whom it may concern.-

Be it known that I, RANsoM E. OLDs, a citizen of the United States, residing at Lansing, in the county of Ingham and State of Michigan, have invented certain new and useful Improvements in Mixing and Controlling Devices for Gas-Engines, of which the following is a specification, reference being had therein to the accompanying drawings.

The invention relates to gas mixing and controlling devices especially designed to be used in connection with gas-engines.

The invention consists in the peculiar construction and arrangement of parts whereby the strength of the explosive mixture is an tomatioally varied according to the speed of the engine, and, further, whereby the gas and air are thoroughly mixed, as more fully hereinafter described and claimed.

In the drawings, Figure 1 is a sectional view of a portion of an engine-cylinder to which the improvements are applied. Fig. 2 is an enlarged section through the valve.

A is the cylinder of a gas-engine.

B is the valve-casing, containing the ind uction-valve O and exhaust-valve D. E is a channel within said casing connecting with the air-inlet port F.

Projecting Within the channel E is a nozzle G, which preferably extends in an angle-bend of the passage E and has a threaded engagement with the valve-casing, as shown in the drawings. This nozzle is of a smaller diameter than the passage E, so as to leave a surrounding annular passage a.

H is a valve-stem extending axially through the nozzle G and through a suitable stuffingbox I out from the casing. This valve-stem is provided with a threaded portion 1), engaging with a corresponding thread in the nozzle. At the inner end of the valve-stem is a head J.

K is a disk valve sleeved upon the stem between the head J and the end of the nozzle. This valve is of greater diameter than the nozzle, so as to have a marginal portion 0 projecting beyond the walls of the nozzle and into the annular passage (1.

L is a spring sleeved upon the head J and hearing at its outer end against a shoulder at thereon,while at its inner end it bears against the disk K.

M is a suitable handle on the valve-stem for operating the same.

The parts being constructed as shown and described, in operation the suction caused by the movement of the piston (not shown) will cause a current of air to be drawn into the passage E, opening the induction-valve O and entering the cylinder. In passing through the annular passage or this incoming air-current will impinge against the project.

ing marginal portion 0 of.the disk valve K. This will cause the latter to be moved inwardly against the tension of the spring L, thereby opening the end of the nozzle G. The gas which is admitted through the con duit N into the nozzle G will thus be drawn into the surrounding air-current, so as to be thoroughly mixed therewith before reaching the cylinder.

It is to be noticed that the degree of opening of the valve K depends upon the velocity of the air-current and that the latter varies according to variation in the speed of the pis ton. Thus if the piston is traveling slowly the valve will be but slightly opened, while the increase in the speed of the piston will cause a greater opening of the valve. By means of the handle M the valve-stem may be adjusted so as to vary the tension of the spring Lupon the valve-disk and also vary the position of the head J in relation to the end of the nozzle. This head forms a stop for limiting the opening movement of the valve K, which may thus be controlled by the handle M.

The gas in passing through the nozzle G will first strike against the flat face of the disk K and will be deflected thereby laterally or transverse to the direction of the incoming air-current. Thus the gas will be forced into said current in the manner to produce a thorough mixing before reaching the cylinder.

What I claim as my invention is 1. In a gas-engine, the combination of a gas-nozzle, a surrounding casing forming an annular air-inlet passage to the cylinder, a disk valve covering the end of said nozzle and having an annular marginal portion projecting beyond the same into the path of the incoming air-current, but being of lesser diameter than said surrounding casing, and a spring for closing said valve, whereby said IO ment of said disk, a spring for pressing said valve to its seat sleeved upon said head and bearing against a shoulder thereon and a casing forming an annular air-inlet passage to the cylinder surrounding said nozzle.

In testimony whereof I affix my signature 15 in presence of two witnesses.
